About game:

Jazz Jackrabbit... Very fast running and shooting action.

Why I did this:

This game is known to be excellent game choice for TASing. With relevant emulator reaching the point where the game can be TASed without noticeable glitching or otherwise bad emulation, I took the task of TASing this.

BIOS/OS/game versions used:

The BIOS/OS versions are identical to 2651S.

Tricks:

Route choices

I follow routes of existing Jazz Jackrabbit speedrun (claimed time 5:00.5 by Wille)... No idea how is that timing determined.

Level comments

Diamondus 1

This level is fairly staightforward running forward. I didn't go through bonus room because there's narrow drop before it that would likely cost more time than it would save.

Diamondus 2

Here there are other things than running. The controls aren't that good, which makes for bit clumsy turnarounds. For some reason the shot I use to shoot the speed upgrade doesn't disappear even if it goes outside the screen (from top).

Tubelectric 1

The tubes downward are annoying... Especially when they hold jazz floating...

Tubelectric 2

More of the same... There would be nice shortcut if one could break out of first pipe into bonus room... Alas, this appears to be impossible.

Medivo 1

Those swords are ocassionally very annoying due to placement. For instance the one after drop in narrow corridor is impossible to shoot and futrhermore damage knockback is blocked, so I need to wait for it to pass. The first spike section the balls swinging on chains just don't co-operate so I take a hit on spikes (fortunately this game does not have instant-death spikes, they just do normal damage).
Then there's the hoverboard section. Annoying to TAS because hoverboard vertical velocity is slow and hoverboard has horizontal inertia... At least it does not have vertical inertia. I also had to pause for moment to avoid getting hit by topmost sword.
This level is long (the only 1 minute+ level in whole episode).

Medivo 2

More of medivo... More complicated level but not much to say except avoid running on spikes even with invincibility (as it runs at slower 5 speed instead of 6) and that last sword is VERY annoyingly timed.

Guardian 1

Just rapid fire missiles into this one (hint: Use lua script). I could jump immediately to start firing but then would get hit by cannon shot so I drop down first. Killing him in middle of jump (even with waiting for him to drop) is faster than waiting for jump to land.

Screenshot suggestions:

Lobbing launcher ammo into electric enemy in level 4.

Final stats:

Length: 04:43.792 Rerecords: 3631.

Nach: Fantastic job, best Sonic run ever. Hope you do another 5 TASs for the other episodes too. Accepting.

I watched the YouTube run prior to it being submitted and I am glad to see the game destroyed in such a fashion. Yes vote. For the record (and the benefit of our encoders): Ilari has encoded this (and his other runs) already and is looking for somewhere to upload them.

Wow, Ilari, you've been pulling off a lot of runs lately! Also, thanks for making and posting the encode on this one. It was certainly a good fast ride through the game, with good music to boot. Nice job!
Used to be a frequent submissions commenter. My new computer has had some issues running emulators, so I've been here more sporadically. Still haven't gotten around to actually TASing yet... I was going to improve Kid Dracula for GB. It seems I was beaten to it, though, with a recent awesome run by Hetfield90 and StarvinStruthers. (http://tasvideos.org/2928M.html.) Thanks to goofydylan8 for running Gargoyle's Quest 2 because I mentioned the game! (http://tasvideos.org/2001M.html) Thanks to feos and MESHUGGAH for taking up runs of Duck Tales 2 because of my old signature! Thanks also to Samsara for finishing a Treasure Master run. From the submission comments:
Shoutouts and thanks to mklip2001 for arguably being the nicest and most supportive person on the forums.

i like the run but give a weak yes vote because i think that a "full game" run should be obselting this one... entertaining as it is, it's still a demo....

I feel very nostalgic about this run. It's been like 14 years since I played this game. I can remember the eyeball enemies and the flying swords... It would be nice to see a full run, though it seems that I only played the first episode. I probably got a demo version back when I played the game. So I don't have any idea about the rest of the game. Was the slow emulation the reason why you only did episode 1? I always wondered why JPCrr is so much slower than DOSbox and why DOSbox can't be made a rerecording version. Yes vote.

Just so you can listen to the rest of the awesome music, I guess. (I think it's an old encoding protocol to let the ending music loop once.) Voted yes since this is one of the games I wanted to see done most (even if it's just episode 1) and Ilari did an amazing job. Anyone who wants to do the rest of the game should talk to him for tips.

I really like the run, but I don't know if I can vote yes for publication for a run that doesn't actually complete the game. I'll abstain from voting for now.
http://www.youtube.com/Noxxa <dwangoAC> This is a TAS (...). Not suitable for all audiences. May cause undesirable side-effects. May contain emulator abuse. Emulator may be abusive. This product contains glitches known to the state of California to cause egg defects. <Masterjun> I'm just a guy arranging bits in a sequence which could potentially amuse other people looking at these bits <adelikat> In Oregon Trail, I sacrificed my own family to save time. In Star trek, I killed helpless comrades in escape pods to save time. Here, I kill my allies to save time. I think I need help.

Duration of the movie The movie must begin from the moment the game boots up (or the movie-begin savestate is loaded), and it must include the full ending and preferably at least one full loop of the ending song.
It follows this to the letter, although it is admittedly not fun to watch, it is following the guidelines. Also adding my yes vote here.

I too wonder if a Jazz submission should include the rest of the episodes as well... Still, this is the most entertaining DOS run so far.

A Yes vote, but like the others I badly want to see the rest of the episodes destroyed in this fashion.

I am (somewhat loudly) of the opinion that the Shareware release of a game is a completely different game than the Registered counterpart. This run completes the Shareware game which includes only Episode 1; the best location for the various Shareware versions is at the Classic DOS Games archive at http://www.classicdosgames.com/game/Jazz_Jackrabbit.html. The Registered version of the game includes all of the episodes and is still available for purchase as linked from the above site. Like others I'd love to see a run of the full registered game but if a full run was created I do not feel it should obsolete this run as they are separate games. I happen to enjoy the ending music and I have no problems with the encode ending where it does, although I also admit that it's not exactly very visually exciting. :) Great work on this run, Ilari - easy Yes vote from me.

I don't understand this argument. Even if they are different games, what does it matter? We don't want to duplicate content in published movies. It's not sensible to have a NES SMB2j run as well as a Super Mario All-Stars Lost Levels run -- even if you think they are separate games, the resultant movies are too similar. Similarly, we don't want to duplicate an entire episode of Jazz Jackrabbit in two separate movies, particularly if that episode is the entire content of one of those movies. Whether the games are the same or not doesn't enter into it -- the acid test is whether the resultant movies are too similar.

dwangoAC, could you elaborate on what makes the game different other than small menu differences?

I'd argue that the differences between SMB2j and Super Mario All-Stars Lost Levels is exactly the kind of example I'm talking about - aesthetically I find them to be very different games that possibly have different frame rules if the comments from that thread can be believed. Certainly HappyLee sees them as different games.

This is where I have to eat my words and potentially apologize for being a nuisance, perhaps even contradicting myself. If the Registered version of the game included the exact episode included in the Shareware version and the gameplay was largely identical I really couldn't argue that they should be separate publications with a straight face. If the two versions contain different glitches, different frame rules, or anything else that prevents the input from the Shareware version from working on the Registered version I'd argue that they are different enough to potentially warrant a case-by-case review of the two to determine if it's worth it to have two versions. My main argument here is that frequently shareware games were released and widely distributed in one version while the registered version contained subsequent fixes for various bugs.

dwangoAC, could you elaborate on what makes the game different other than small menu differences?
Again, I'm going to have to eat my words here. You're right, Jazz Jackrabbit doesn't really have any significant differences between the two. Some shareware games do have substantial differences but.. well, this one isn't one of them when it comes right down to it. I'll go be quiet now... :) A.C. ******
I was laid off in May 2023 and became too ill to work this year and could use support via Patreon or onetime donations as work on TASBot Re: and TASBot HD is stalled. I'm dwangoAC, TASVideos Senior Ambassador and BDFL of the TASBot community; when healthy, I post TAS content on YouTube.com/dwangoAC based on livestreams from Twitch.tv/dwangoAC.

Speaking of versions, is this 1.0, 1.1, or 1.3?
TASing or playing back a DOS game? Make sure your files match the archive at RGB Classic Games.

I think it is v1.0 (VENDOR.DOC claims so, I haven't found version number from other places).

Excelent run. I have to say, I'm excited to see all of these classic DOS games (that I never knew anyone else ever actually played) showing up here. I can't wait for the next!
